EYELET.

SPECIFICATION formingpart of Letters Patent No. 698,770, dated April 29,1902. Application filed $eptember 11,1901. Serial No. 75 ,021. (Nomodel.)

To all whom, it rnctg concern.-

Be it known that LHERMAN G. WEIBEZAHL, a citizen of the United States,and a resident of the borough of Manhattamcity, county,and State of NewYork, have invented certain new and useful Improvements in Eyelets; andI hereby declare the following, taken in con junction with theaccompanying drawings, to be a full, clear, and exact description ofsame.

The subject of the present invention is an improved eyelet for fasteningtogether thicknesses of paper or other material, and has for its primaryobject the production ofan article of a class referred to which when setwill in addition to its normal flange at one end present at the other ahead formed by the laterally-spread metal eifected by the compressionsustained during the setting operation.

To this end the invention consists in part of an eyelet having a normalbase-flange and with the metal at the other open end so strengthenedthat when the eyelet is compressed in the setting operation suchstronger metal portion will cause the weaker metal contiguous thereto tospread laterally and present a highly satisfactory head.

There are other novel features connected with my invention which arefully disclosedhereinafter.

In the accompanying drawings, forming part of this specification, Figure1 is a plan view, on an exaggerated scale, of a blankindieating thepartial formation. of one form of eyelet embodying my invention. Fig. 2is a vertical elevation of the eyelet completed from the blankillustrated in Fig. 1. Fig. 3 presents a top view of the eyelet beforebeing crushed, while Fig. 4: illustrates the same when crushed, showingthe head formed by the laterally-spread barrel. Fig. 5 represents myeyelet in two positions, partially set and completely set in the paper.Both views are shown in section. In Fig. 6 is shown a section of thehead of the eyelet, showing in detail the formation of the fortifiedring portion constituting the eye of the improvedeyelet. Fig. 7 is avertical sectional view of another form of eyelet embodying myinvention, the slits being omitted and the dotted lines indicating thespread portion forming the head. Fig. 8 is a vertical side elevation ofanother form of improved slitted eyelet, the portion to form the headbeing represented as partially spread. Fig. 9 is a vertical sectionalview of the form shown in Fig. 8 before being spread. 1 Similarreference characters designate corresponding parts in the severalfigures.

Referring more particularly to Figs. 1 to 6, the blank from which theeyelet is to be formed is of thin metal and comprises a central portionA, from which extend a series of "radial members B, each terminating inasector-shaped end 0, as indicated in Fig. 1. The metal of the centralportion A immediately surrounding the opening A therein is turned overto present an annular curled beading A around the said opening, whichconstitutes a ring carrying the eye of the eyelet. The members B arebent right-angular to the portion A, with their edges closely adjacentto each other to constitute a barrel B, open at portions of the barrelto cause the latter to collapse and spread outward laterally to form asatisfactory head, as shown in Fig. 4. The outwardly bend of the memberscomposing the-barrel is assured by the pressure of the stronger ordoubled'portion of the beading forming the eye; but an anvil on springsupon which theeyelet is designed to be set makes the collapsing inwardlyof the members an impossibility.

In Fig. 7 the barrel and its flange are unslitted, the stronger metal'atthe other open end being secured by contracting. the eyelet to obtain atapering portion D. This is done in the drawing process,the barrel beingdrawn relatively thinner than the tapering portion, as shown, which isnot crimped or otherwise weakened. The angle at which it is set inrelation to the barrel. assures the outward spread of the latter.

Figs. 8 and 9 illustrate the arrangement for securing the stronger metalat the end where the head is to be formed, the same as in Fig. 7, thebarrel being provided with slits E, which do not extend to the normalflange of the eyelet.

As-thus explained, it will be appreciated that an eyelet produced inaccordance with my invention can be quickly and efficiently applied andset and can be made and sold in quantities at a cost comparing favorablywith other types now in use, while presenting advantages possessed by noothers.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An eyelet comprising segmental arms constituting thencrmal flange andthe barrel of the eyelet, with a partially-closed and stronger upperportion constituting its end.

2. An eyelet, the barrel of which has at one of its open ends aninwardly-extending and immediately contiguous flange, the said barrelweaker than the said flange, and anorinal base extending outwardly fromthe said barrel. 1

3. -An eyelet presenting a normal flange at one of its open ends, andconstituting the base, the upper end of the eyelet presenting the eyeand a flange stronger than the metal of the barrel immediatelycontiguous thereto, said stronger upper portion capable, uponcompression, of causing the metal of the barrel to collapse.

4. An eyelet, the barrel of whichhas at one of its open ends aninwardly-extending flange,

the metal of said barrel immediately contigu stronger metal portion thanthe barrel im me diately contiguous thereto and capable of spreading thesaid slitted barrel outwardly upon compression, and form a head. v

6. A sheet-metal eyelet comprising members terminating in sector-shapedends with a central portion perforated to form, with its surroundingmetal, the upper end of the eyelet; the said members forming a barrelwith a normal flange presented by the sector-shaped ends, the said upperend of the eyelet involving a-stronger metal portion than theimmediately-contiguous barrel which, weakened.

by the slits, and spread outwardly by com eye being stronger than thebarrel metal immediately contiguous thereto.

8. An eyelet having a heading around one of the open ends of the barrel,said beading designed to render the metal stronger thereat and adapted,when subjected to compression, to spread the contiguous weaker metal ofthe barrel to form ahead.

9. An eyelet having a normal flange at one end of its barrel and abeading around the other open end thereof, said beading rendering themetal stronger thereat and adapted, when subjected to compression, tospread the contiguous weaker metal of the barrel toform a head.

10. An eyelet'with a slitted barrel and a beading around the upper endthereof, said beading rendering the metal stronger thereat,

and adapted, when subjected to compression, to spread the contiguousslitted and consequently weaker metal of the barrel to form the head.

11. An eyelethavinga normal flange at one end of a slitted barrel and abeading around the other open end thereof, said beading rendering themetal stronger thereat and adapted, when subjected to compression, tospread the contiguous slitted and consequently weaker metal of thebarrel to form the head.

12. An eyelet stamped out of sheet metal and pressed into a barrel, openat both ends,- one of the said ends equipped with a heading around thesame formed of the metal displaced to form the .eye, the said beadingdesigned to cause the barrel to spread outward in those portions .of theeyelet extending" above the material to be fastened together,

7 and form a broad bearin g against the said material. I p

13. An eyelet stamped out of sheet'metal and formed into a barrel with aflange at one of its open ends and a beading formed by the metaldisplaced to constitute the other open end, the said beading designed tocause the barrel to spread outward in those portions of the eyeletextending beyond the material to be fastened together, and form a broadbear-
